EN 1092-1

The current DIN standards for flanges have been replaced by the new Euronorm: EN 1092-1. For all flanges, one and the same EN standard applies. To identify the difference between the various flange shapes, such as front flanges and flat sealing flanges, the EN 1092-1 uses various "type" indications.
